Apple Watch can help detect COVID-19 positivity

According to new research, the Apple Watch may be able to detect whether the wearer has COVID-19 days before it is diagnosed or symptoms of the infection appear.

Medical researchers from Mount Sinai Health System in New York they found out that theApple Watch can detect subtle changes in heart rhythm of a user up to seven days before the infection can be detected through testing.

The study looked at the variation over time between heartbeats, a metric known as heart rate variability, which helps understand how a person’s immune system works.

We already knew that heart rate variability markers change as inflammation develops in the body, and COVID-19 is an incredibly inflammatory event. This allows us to predict that people are infected before they know it“Said one of the managers of the study.

When it comes to COVID-19, infected people experience less heart rate variability than those who tested negative. The study followed 300 Mount Sinai Health System health workers who wore the Apple Watch for five months.

Another study from Stanford University in California looked at a variety of activity trackers made by Apple, Fitbit, Garmin and other manufacturers as a way to understand the presence of a possible COVID-19 infection. This research, published in Nature Biomedical Engineering, found that 81 percent of those who tested positive for the coronavirus experienced changes in resting heart rate. The researchers found that the trackers could detect an infection up to nine and a half days before symptoms began.

According to Stanford University professor Michael Snyder, one of the main benefits of wearable trackers is that users wear them constantly throughout the day. This could help eliminate some of the drawbacks of standard coronavirus tests.

The team also developed a alarm system that alerts users if their heart rate has been elevated for an extended period of time. This parameter could alert people and prompt them to cancel their exit or any meeting, as they could be contagious.

Right now, we’re relying on people who say they’re sick and aren’t feeling well, but wearing an Apple Watch doesn’t require any active input from the user and can identify people who may be asymptomatic. It’s a way to better control infectious diseases “concluded Hirten.

Will we ever be able to make the most of this research also in Italy?
